Hello.

The answer is A. The Declaration of Rights.

Answer:

c. image of the state flag

Answer:

the value of x and y is 3 and -1 respectively.

Step-by-step explanation:

from the question

let

2x + 3y = 3........................ equation 1

y = 8 - 3x.............................. equation 2

put y = 8 - 3x in equation 1

2x + 3y = 3........................ equation 1

2x + 3 ( 8 - 3x) = 3

2x + 24 - 9x = 3

24 - 7x = 3

24  = 3 + 7x

24 -3 = 7x

21 = 7x

divide both sides by 7

x = 3

put x = 3 in equation 2

y = 8 - 3x.............................. equation 2

y = 8 - 3 ( 3)

y = 8 -9

y = -1

therefore the value of x and y is 3 and -1 respectively.

The each class is 64 minutes or 1 hour 4 minutes long.

Step-by-step explanation:

1 hour = 60 minutes.

Time spent in 6 classes :

Time spent in 6 classes = Total time - (lunch period + switching classes)

⇒ 456 - (30+42)

⇒ 456 - 72

⇒ 384 minutes.

The Time for each of 6 classes :

Time for each class = Time spent for all 6 classes / 6

⇒ 384/6

⇒ 64 minutes.

⇒ 1 hour 4 minutes.

Answer: -6

Explanation: In this problem, we're given the function f(x) = 3x - 12 and we're asked to find f(2).

To find f(2) or the value of the function when x equals 0, we simply substitute 2 in for x in our function. So we have f(x) = 3(2) - 12 or 6 - 12 which equals -6.

So f(2) or the value of the function when x equals 2 is -6.

Final answer:

When x equals 813, the algebraic expression x⋅5⋅25⋅4÷5 simplifies to 81300 by substituting x with 813 and following the order of operations through multiplication and division.

Explanation:

The question asks for the calculation of an algebraic expression with the substitution of x=813. The expression is x⋅5⋅25⋅4÷5. To solve this, we first substitute x with 813, and then we follow the order of operations.

Therefore, when x=813, the solution to the expression is 81300.

Answer:

[tex]f=17\\p=9\\[/tex]

Step-by-step explanation:

Let

[tex]f= Full-time\\p=Part-time[/tex]

Full time rates-$275, Part-time rates-$140

The problem can be expressed as:

[tex]f+p=26...eqtn1\\275f+140p=5935....eqtn2\\[/tex]

Express eqtn1 in terms of f,[tex]f=26-p[/tex]

Answer:

[tex]g(x) = x + 6[/tex]

Step-by-step explanation:

The parent function is given as:

[tex]f(x) = x + 8[/tex]

We want to find a new function that results after shifting f(x), 2 units to the right.

Let that function be g(x), then

[tex]g(x) = f(x - 2)[/tex]

We replace x by x-2 in f(x) to get:

[tex]g(x) = x - 2 + 8[/tex]

When we simplify, we obtain:

[tex]g(x) = x + 6[/tex]

Answer:

5 ≤ h<7

Step-by-step explanation:

the rider has to be more than at least 5 feet tall, so h is greater than or equal to 5 (5 ≤ h), but they have to be less than 7 feet tall (h<7) so, therefore, we get 5 ≤ h<7

Solution:

Let stamps be s and postcards be p

Given that,

The number of stamps was 4 more than twice the number of postcards

s = 4 + 2p -------- eqn 1

Jason bought both 41-cent stamps and 26-cent postcards and spent $10.28

41 cent = $ 0.41

26 cent = $ 0.26

Therefore,

[tex]s \times 0.41 + p \times 0.26 = 10.28[/tex]

0.41s + 0.26p = 10.28 --------- eqn 2

Substitute eqn 1 in eqn 2

0.41(4 + 2p) + 0.26p = 10.28

1.64 + 0.82p + 0.26p = 10.28

1.08p = 10.28 - 1.64

1.08p = 8.64

Divide both sides by 1.08

p = 8

Substitute p = 8 in eqn 1

s = 4 + 2(8)

s = 4 + 16

s = 20

Thus Jason bought 20 stamps and 8 post cards

Final answer:

To solve the system of equations (x + y = 7 and 2x - y = -1), use the addition method to find that the solution is x = 2 and y = 5.

Explanation:

The question asks for the solution to the following system of equations:

x + y = 7

2x – y = – 1

To solve this system, we can use the method of addition (also known as elimination) to eliminate one of the variables. Here's how:

Add the two equations directly to eliminate variable y:
(x + y) + (2x - y) = 7 – 1
3x = 6
Therefore, x = 2.

Substitute the value of x into one of the original equations to find y:
2 + y = 7
Therefore, y = 5.

So, the solution to the system of equations is x = 2 and y = 5.

The solution to the system of equations is [tex]x = 2[/tex] and [tex]y = 5[/tex].

To solve the system of equations [tex]x + y = 7[/tex] and [tex]2x - y = -1[/tex], we can use a method called substitution or elimination. Let's use substitution for this case.

Start with the first equation:
[tex]x + y = 7[/tex]

Solve this equation for one of the variables, say [tex]y[/tex]:
[tex]y = 7 - x[/tex]

Substitute [tex]y = 7 - x[/tex] into the second equation:
[tex]2x - (7 - x) = -1[/tex]

Simplify and solve for [tex]x[/tex]:
[tex]2x - 7 + x = -1[/tex]
[tex]3x - 7 = -1[/tex]
[tex]3x = 6[/tex]
[tex]x = 2[/tex]

Substitute [tex]x = 2[/tex] back into the expression for [tex]y[/tex]:
[tex]y = 7 - 2[/tex]
[tex]y = 5[/tex]

This means that the point [tex](2, 5)[/tex] is where the two lines represented by these equations intersect. Therefore, the solution is [tex](2, 5)[/tex].

Answer: 648, 1,944, and 5,832.

Step-by-step explanation: Begin by studying the pattern.

Here, notice that 8 × 3 is equal to 24.

24 × 3 is equa to 72.

72 × 3 is equal to 216.

Continuing the same pattern, 216 × 3 is equal to 648.

648 × 3 is equal to 1,944.

1,944 × 3 is equal to 5,832.

I have also attached in image below showing my work.

So the three missing terms in the pattern are 648, 1,944, and 5,832.

Step-by-step explanation:

Answer:

525 Minutes

Step-by-step explanation:

The equation would be...

$60 + $0.12m = $123

Now we can simplify

($60 - $60) + $0.12m = ($123 - $60)

$0.12m = $63

($0.12m/$0.12) = ($63/$0.12)

M = 525

Answer:

-59

Step-by-step explanation:

x3 is meaningless; I assume you meant x^3.  

If that's the case, then:

3x + 8 = -4 is equivalent to 3x = -12, so that x = -4.

Then (-4)^3 + 5 = -64 + 5 = -59

Answer:

-59

Step-by-step explanation:

the question can be solved by some simple mathematical steps.

If 3x + 8 = -4

then, x3 + 5 =?

from 3x + 8 = -4

collect the like terms

3x = -4 - 8

3x = -12

divide both sides by 3

3x/3 = -12/3

x = -4

if x = -4 then to find  x3 + 5 will imply that we will insert the value of x = -4 into the x3 + 5

-4 ³ + 5

-64 + 5

= -59

therefore the value of x3 + 5 is solved to be -59

Answer:

-8.5, or -8 1/2

Step-by-step explanation:

Put it into an improper fraction: -17/4

Multiply: -17/4 * 2/1 (To divide, multiply by reciprocal)

= -34/4

Simplify: -17/2, or -8 1/2

Answer:

-34/4    or -8 1/2

Step-by-step explanation:

First we want to put -4 1/4 so its all a fraction we do this by multiplying 4 to 4 and adding it to the 1 already in the fraction (We can ignore the sign and just add it to the fraction because the entire fraction is negative not just the 4). So we have -17/4

To divide fractions we use keep change flip it is an easier way to divide fractions with out making decimals. We keep the first fraction change the division into multiplication and flip the last fraction, in this case 1/2 becomes 2/1. Now we have

-17/4 * 2/1  

Our next step is to multiply the numerators together and the denominators together and then put it back in fraction form.

-17 * 2 = -34

4 * 1 = 4

Our final result is

-34/4        

Or if you need it as a mixed number you just divide the 34 into 4 as many times as you can and make that the whole number. 34 doesn't completely fit into 4 but 32 does so we have

-8 2/4      or simplified further

-8 1/2

Answer:

$72.45

Step-by-step explanation:

Add the amounts of the manicure and pedicure together: 28 + 35 = 63

Then find 15% of $63. You will need to find the decimal equivalent of 15%. To do this, divide 15 by 100 or move it two decimal places to the right: 15/100 = 0.15

Now, multiply total of the manicure and pedicure, 63, by 0.15: 63 x 0.15 = 9.45

$9.45 will be her tip. To find the total amount Skylar payed, add the tip to the amount spent on the mani/pedi: 63 + 9.45 = 72.45

Skylar will pay $72.45

Hope this helps!

Final answer:

To calculate Skylar's total payment including a 15% tip for her manicure and pedicure, add the cost of both services ($63) and then calculate the tip ($9.45). The total payment is $72.45.

Explanation:

The student's question involves calculating the total cost of a service which includes both a tip and the original prices of the services purchased - in this case, a manicure and a pedicure. To find how much Skylar will pay after tipping 15%, we first need to calculate the total cost of the services before the tip.

Firstly, we add the cost of the manicure ($28) and the pedicure ($35) to get the total cost before the tip:

Next, we calculate the amount of the tip by multiplying the total cost by the tip percentage (which we convert from 15% to a decimal by dividing by 100):

Finally, we add the original total cost to the tip to find the final amount Skylar will pay:

So, Skylar will pay $72.45 in total for her manicure and pedicure including a 15% tip.
